Hey all,
So for the last few weeks while I’ve worked on Discourse, I noticed that sometimes while scrolling up and down, the top nav bar will freak out and start flickering like crazy even if you aren’t moving the page. We’ve verified this on the dev site and I’ve verified it here on Meta. It’s a hard thing to showcase unless you’ve seen it since it’s so random. It’s happened on my desktop, and here in my phone. I’ve had it several times today, enough to warrant a big topic.
I’m screen recording where I can on my iPhone to get it. It’s really inconsistent but when it does happen, it triggers my motion sickness :(.
Edit: I think it has something to do when you scroll past the first post and it switches to the smaller logo, but I’ve more consistently triggered it back by slowly scrolling up from any post, so I’m not sure if that’s useful.
